Deployments history improvements

[clemlak]

Description

Our script generating the deployments history could use some improvements.

Motivation

Yes, a lot of motivation.

Proposed Solution

Here is a list of the potential improvements:

• List of "blacklisted" contracts: mainly useful for test networks, we might want to hide some contracts that were deployed previously and are not longer relevant
• Order chains by name: in the main deployments file Deployments.md, the chains might not be ordered by names (Unichain being displayed before Base for example)
• Order deployments by date: for some reason the deployment files dedicated to each chain (in the deployments folder) are not order chronologically
